Mapping, monitoring and modelling permafrost change in the NWT
Principal Investigator: Kokelj, Steve V
Licensed Year(s): 2025 2024 2023 2022 2021
Summary: This licence has been issued for the scientific research application No.5473. The primary objectives of this research are: 1) to develop and test new methods of characterizing permafrost and monitoring permafrost landscape change with a focus on the Beaufort Delta, central Mackenzie Valley and North Slave regions; 2) mapping sensitive permafrost terrain across NWT by integrating expert assessme...


Instrumentation and thermal monitoring of the Gunghi Creek Arch Bridge Replacement
Principal Investigator: Beddoe, Ryley
Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No.5466. The objectives of this research are to: 1) monitor the thermal regime of the embankment, arch, piles and road subgrade post the construction of the arch replacement; 2) use measured ground temperatures to calibrate numerical models for understanding and predicting bridge, road and embankment stability; 3) analyze mult...


Invertebrate paleoecology of the Mackenzie River uplands region
Principal Investigator: Medeiros, Andrew
Licensed Year(s): 2023 2022
Summary: This licence has been issued for the scientific research application No.5455. To examine the effects of flooding and permafrost changes on the ecological function and structure of differing lakes in the Mackenzie River uplands region. The research team will drive to sites along the Inuvik-Tuktoyaktuk Highway to collect 1 litre water samples from a small boat. The research team will be using...


Murky waters: Impacts of disturbances on the mobilization and downstream delivery of mercury and methylmercury
Principal Investigator: Olefeldt, David
Licensed Year(s): 2023 2022 2021
Summary: This licence has been issued for the scientific research application No.5448. This project proposes to monitor wetlands, streams, rivers, and lakes in the Dehcho region, with a focus on understanding current and future trends in aquatic mercury and methylmercury. The region has vast stores of mercury accumulated in organic wetland soils, and there is a risk that disturbances such as permafrost ...


Glacier mass balance of the Melville South Ice Cap
Principal Investigator: Burgess, David O
Licensed Year(s): 2023 2022 2021 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: This licence has been issued for the scientific research application No.5450. The objectives of this integrated monitoring and research project is to provide 1) science based knowledge pertaining to the patterns and rates of climate change, and 2) a quantitative basis for estimating Canada’s contributions to global sea-level rise. Glacier mass balance is defined as the difference between th...


Arctic Great Rivers Observatory 4
Principal Investigator: Holmes, Robert M
Licensed Year(s): 2024 2023 2022 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: This licence has been issued for the scientific research application No.5441. The Arctic Great Rivers Observatory project studies the six largest rivers in the Arctic: the Mackenzie and Yukon Rivers in North America, and the Ob', Yenisey, Lena, and Kolyma Rivers in Russia. The research team are interested in understanding how climate change is impacting Arctic rivers. The team take measurements...


Characterising the mineralisation of the Colomac and Goldcrest deposits and the Leta Arm Group of the Indin Lake supracrustal belt.
Principal Investigator: McBride, John A
Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No.5429. The objective of this research is to better understand the lithological host rocks, mineralization controls and timing of the intrusions at the Colomac Deposit, Goldcrest Deposit and the broader supracrustal rocks that host gold mineralization within the greenstone belt. This added understanding will support further d...


Measuring and simulating permafrost thaw
Principal Investigator: Gruber, Stephan
Licensed Year(s): 2023 2022 2021
Summary: This licence has been issued for the scientific research application No.5425. The objectives of this project are to understand: 1) how permafrost differs in temperature and chemical/physical characteristics from place to place; 2) how these different types of permafrost react to change (climate/disturbance); and, 3) which future changes in permafrost are likely and which are less likely based o...


Vulnerability of northern drinking water sources to environmental change
Principal Investigator: Comte, Jerome
Licensed Year(s): 2023 2022
Summary: This licence has been issued for the scientific research application No.5418. The overarching goal of this project is to assess the implications of climate change on drinking water quality and practices, and to implement a community-based monitoring program. Specifically, the research team will: 1) engage and work with local communities to co-design and undertake a drinking water quality monito...


Characterization of recent permafrost landslides and ground ice distribution in the central Mackenzie Valley, NWT
Principal Investigator: Froese, Duane G
Licensed Year(s): 2024 2023 2022 2021
Summary: This licence has been issued for the scientific research application No.5423. This work builds on studies over the last several years, including field work in the Mackenzie River valley in 2018 and 2019. The objective of 2021 fieldwork is twofold: 1) characterizing a large suite of retrogressive thaw slumps and thaw-induced landslides in the Redstone, Keele, and Johnson River basins that have i...
